Wrasses


The wrasses are marine fishes, which belong to the family, Labridae. Many of the species of this family are beautiful and bright-colored. This family is very large and consists of over 600 species in 82 genera. These are further divided into nine subgroups or tribes. These fishes are usually small and most of them grow up to a size of less than 20 cm in length. These fishes are carnivores and feed on wide range of small invertebrates. These species can be recognized by their thick lips. Wrasse fish have protractile mouths and separate jaw teeth. They have distinct jaw characteristics. The inside of the lips are curiously folded. Their dorsal fin consists of (8 to 21) spines and (6 to 21) soft rays. Wrasses live in the Atlantic, Indian, and Pacific Oceans. They are usually found in the shallow water habitats such as coral reefs and rocky shores.

Wrasses Reproduction / Breeding
These wrasses are found to be hermaphrodites, which means they can behave with either of the characteristics, i.e., male or female. There are three different mating systems in these species namely lek-like, polygynous, and promiscuous mating systems. As they are hermaphrodites they spawn in pairs and group. Large amount of eggs are released in the mating process. Their planktonic eggs move with the tidal currents and thus have no relation to their adults.
